channel plugAlthough abandoned channels are common and identifiable features in alluvial plains, their detailed internal architecture remains overlooked, particularly their coarse permeable compartment, with implications for underground water flow. The actively shifting gravel‐bed Ain River (France) provides ...
To this end, we examined the grain-size characteristics of the Holocene black soil across the plains in Northeast China, and we conducted optically stimulated luminescence (OSL) dating of the underlying stratum. The western Holocene black soils have a bimodal grain-size distribution similar to that...
Mapping Quaternary siliciclastic depositional units on low-relief coastal plains historically has been based on aerial photographs. Ac- curacy and detail have been hindered, however, by lack of exposure and low relief. High -resolution airborne lidar surveys, along with surface and borehole ...
The study revealed that tilting of the Gandak tectonic block caused eastward shifting of the Gandak River by ~80 km, which consequently formed older fluvial plains from east to west. However, little emphasis was given on recognizing and explaining the younger geomorphic units and their ...
Geomorphology of Depositional SurfacesThe geomorphology of depositional surfaces has been slow in developing. Adequate knowledge of deltas, deltaic plains, sand dunes, and eolian plains is very recent. Text books are still somewhat behind in adequate treatment of depositional geomorphology....
Stable or falling sea level in the same time frame, a pattern typical of the Southern Hemisphere, is associated with a lower abundance of islands and a higher percentage of islands along deltas rather than coastal plains. Both coastal plain and deltaic island morphology are sensitive to the ...
Depositional Models for Braided Alluvium Brian R. Rust Abstract Braided alluvial deposits form in rivers and on alluvial fans and plains, and comprise three lithotypes: gravel-, sand- and silt-dominant. The gravel lithotype is characterised by framework-supported gravel, which in proximal deposits ...
